Mined diamond compared to laboratory grown diamond

Mined Diamond and laboratory grown diamond

Diamonds have long been a symbol of love, luxury, and status. However, in recent years, there has been a growing interest in the production of laboratory-grown diamonds as a more ethical and sustainable alternative to mined diamonds. In this article, we will explore the differences between a mined diamond and a laboratory-grown diamond.

Mined Diamonds:

Mined diamonds are formed naturally over millions of years deep beneath the earth’s surface. These diamonds are found in mines, usually in remote locations, and are extracted using heavy machinery and explosives. The mining process is often associated with negative environmental and social impacts, such as habitat destruction, water pollution, and exploitation of workers.

Mined diamonds are valued for their rarity and unique characteristics. The quality of a diamond is determined by the 4Cs – cut, clarity, carat weight, and colour. The more perfect a diamond is in each of these categories, the more valuable it is considered to be.

Laboratory-grown Diamonds:

Laboratory-grown diamonds are created using advanced technological processes that mimic the natural formation of diamonds. These diamonds are produced in a laboratory environment, where conditions are controlled and monitored to ensure consistent quality and purity.

The process of creating a laboratory-grown diamond involves using a small diamond seed, which is placed in a chamber and exposed to extreme heat and pressure. Over a period of weeks, carbon atoms are deposited onto the seed, gradually building up the crystal structure of the diamond.

The resulting laboratory-grown diamond is physically and chemically identical to a mined diamond, and can be graded using the same 4Cs criteria.

Differences between Mined Diamonds and Laboratory-grown Diamonds:

Mined diamonds and laboratory-grown diamonds have very similar chemical properties, as they are both made of pure carbon atoms arranged in a crystalline structure. However, there are some subtle differences in the impurities and defects that can be present in each type of diamond.

Mined diamonds can contain trace elements such as nitrogen, boron, and hydrogen, which can affect the diamond’s colour and other properties. Laboratory-grown diamonds can also contain these impurities, but they can be controlled more precisely during the growth process to produce diamonds with specific colours and properties.

One key difference between mined and laboratory-grown diamonds is the presence of defects in the crystal structure. Mined diamonds can contain defects such as vacancies, dislocations, and impurity atoms, which can affect the diamond’s hardness and other physical properties. Laboratory-grown diamonds are typically more pure and have fewer defects, which can make them more consistent in their properties and easier to work with for industrial and scientific applications.

In terms of their chemical composition, both mined and laboratory-grown diamonds are made of pure carbon, with each carbon atom bonded to four neighboring carbon atoms in a tetrahedral arrangement. This gives diamonds their unique hardness and other physical properties, as well as their optical properties such as high refractive index and dispersion.

Overall, while there are some subtle differences in the impurities and defects that can be present in mined and laboratory-grown diamonds, they are both essentially the same material in terms of their chemical properties.

One of the key differences between mined diamonds and laboratory-grown diamonds is their origin. Mined diamonds are natural, formed over millions of years in the earth’s mantle. Laboratory-grown diamonds, on the other hand, are created using advanced technological processes in a laboratory.

Another difference is the environmental and social impact of the two types of diamonds. Mined diamonds are often associated with negative environmental and social impacts, such as habitat destruction, water pollution, and exploitation of workers. Laboratory-grown diamonds, on the other hand, are generally considered to be more sustainable and ethical, as they do not involve the same level of environmental destruction or human exploitation.

Finally, there is a difference in price between mined diamonds and laboratory-grown diamonds. Mined diamonds are generally more expensive, due to their rarity and the high costs associated with mining and extraction. Laboratory-grown diamonds, on the other hand, are often less expensive, as they can be produced in larger quantities and do not require the same level of mining and extraction.


Mined diamonds and laboratory-grown diamonds both have their pros and cons. While mined diamonds are valued for their rarity and unique characteristics, they are often associated with negative environmental and social impacts. Laboratory-grown diamonds, on the other hand, are more sustainable and ethical, but may be less valuable due to their artificial origin. Ultimately, the choice between a mined diamond and a laboratory-grown diamond comes down to personal values and priorities.

China’s largest jewellery retailer backs mined diamonds

Chow Tai Fook 

The Natural Diamond Council (NDC), which groups the world’s seven leading diamond producers, has inked a deal with China’s top jewellery retailer Chow Tai Fook to boost demand for mined rocks in the Asian market.

The partnership, the trade organization’s first collaboration with a retailer, seeks to attract young Chinese customers to naturally produced diamonds.

It also comes as Chow Tai Fook, which has more than 4,500 stores in East Asia and the United States, plans to expand its global footprint.

“One of our key priorities this year is to work closely with natural diamond retailers to protect and convey the authentic and unique beauty of natural diamonds together,” David Kellie, CEO of the Natural Diamond Council, said in the statement.

“I am confident that this partnership will solidify the values of and forge consumers’ desire for natural diamonds,” Chan Sai-Cheong, managing director (Mainland China) of Chow Tai Fook Jewellery Group added.

Earlier this month, the world’s biggest jeweller Pandora dealt a blow to diamond miners by announcing it would no longer sell mined gems, but exclusively man-made ones.

Since 2011, when prices peaked thanks to China’s younger shoppers, diamonds have faltered. Lab-grown stones, initially priced confusingly close to the real thing, posed a challenge.

The NDC, until 2020 known as the Diamond Producers Association, focuses on marketing mined rocks and its funded by its members: ALROSA, De Beers, Dominion Diamonds, Lucara Diamond, Petra Diamonds, Rio Tinto and RZM Murowa.

D1 Mint buys 1500 investment quality diamonds for new diamond backed crypto coin

investment grade diamonds

The emergence of blockchain technology is helping to turn diamonds into a new investment asset class that in turn, could drive future demand for natural diamonds, the creator of a new diamond backed crypto coin said on Friday.

Singapore based D1 Mint Limited, the creator of the diamond backed D1 Coin, announced on Friday that it has signed a purchase order with diamond cutting and polishing company KGK Diamonds to start its diamond reserve with 1 500 investment-grade diamonds delivered by Russian diamond producer Alrosa, valued at close to $20 million, and which are deposited at a vault in Antwerp, Belgium, the global centre for the diamond trade.

“Today we made a huge step forward in the development of D1, a project started a year ago to create an asset backed token and to make diamonds an investable asset class,” D1 founder Hogi Hyun said.

The purchase order is meant to establish a reserve for digital tokens backed by gem quality diamonds certified by the Gemological Institute of America (GIA). Each D1 Coin is pegged to the value of a fraction of an authentic, natural diamond, as determined by the proprietary pricing algorithm, the D1 Matrix.

According to D1 Mint, diamonds are an ideal asset backing for a coin since they are rare, taking a billion years to develop, and have several millennia of history as a recognised store of wealth and value.

The diamonds in the D1 reserve will be sent to GIA in New York to be graded, laser-etched and packed in tamper proof packaging, before being shipped to secure vaults in Singapore and Switzerland. Logistics and warehousing are provided by established specialists such as Brinks and Malca Amit, while insurance is provided by Lloyds of London.

Further, D1 Coins provide users the ability at any point in time to select specific diamonds from the diamond reserve and convert their tokens into diamonds at a fixed price determined by D1 Matrix. D1 Coins provide a direct exposure to the price of diamonds, opening a new asset class to investors globally. In addition, as an asset-backed token, the D1 Coin provides an excellent means of exchange and store of value in the crypto markets.

Alrosa noted that the approach taken by D1 “will succeed in making natural diamonds an investment asset class attractive to various investor groups, drive higher demand for natural diamonds and support further growth of the diamond industry in Russia”, Alrosa board member and D1 advisory committee member Alexei Chekunkov noted.

“The convenience of blockchain will help turn diamonds into a respectable investment asset class that in turn will drive future demand for natural diamonds.”

Independent New York diamond analyst Paul Ziminisky noted in comments to Mining Weekly Online that the potential for new diamond demand is there, but blockchain does not necessarily address the traditional challenge of investing in physical diamonds with its fungibility, or lack thereof.

“I think the success of products like these will rest on the reputation of the funds and the custodians, for example, confidence that the underlying asset is accurately reflected in the coin. This can be mitigated somewhat with auditing.”

According to him, gold has done quite well in securitised form, and he believes that this is in part due its fungibility, and the simplicity that comes with that. “So gold has a natural advantage relative to diamonds as a securitised physical investment vehicle in that sense.”

“In general, I see securitised forms of physical commodities more as trading vehicles than investments. I think the inherent desire to hold physical diamonds as an investment, or as a store of value significantly rests in the desire to physically possess the asset,” Zimnisky commented.
